XNMF090612‑F57 WKK25G milling indexable insert — Tiger·tec Gold for cast iron, Walter Tools

The XNMF090612‑F57 WKK25G is a coated carbide milling insert optimised for machining cast iron with controlled chip formation and high wear resistance.

• Tiger·tec Gold coated carbide
• Optimised for cast‑iron machining
• Chipbreaker F57 for reliable chip control
• 0° negative rake with 1.2 mm corner radius

Durable performance for abrasive cast‑iron work

The Tiger·tec Gold grade WKK25G combines a coated carbide substrate with a wear‑resistant coating engineered for the abrasive nature of cast iron. This results in extended tool life, reduced downtime and a lower cost per part when compared to uncoated grades. The insert’s design focuses on stable cutting under intermittent loads typical of cast‑iron components, so production cycles maintain consistent output and predictable re‑grinding intervals.

Geometry that improves stability and surface quality

A 0° negative rake and a 1.2 mm corner radius create a robust cutting edge that resists chipping and deflection. Negative rake geometry increases edge strength for interrupted or heavy cuts, while the larger corner radius contributes to improved workpiece finish and dimensional stability. The tolerance class M ensures repeatable seating in the toolholder, supporting consistent part quality across multiple insert changes.

Optimised chip control for secure machining

The chipbreaker F57 is tailored to the short, brittle chips produced when machining cast iron, promoting dependable chip breaking and evacuation. Effective chip control reduces the risk of recutting, minimises tool‑holder contamination and shortens cycle times through fewer manual interventions. Combined with the fast replacement capability of indexable inserts, this optimises overall machining efficiency and supports uninterrupted process flow.

Compatibility, handling and recommended use

The insert fits toolholders designed for the XNMF090612‑F57 format and is intended primarily for ISO group K (cast iron) applications. Its coated carbide construction makes it suitable for abrasive grey and nodular cast irons where stable chip formation is required. For new operations, trial runs with adjusted feeds and depths are advised to exploit the grade’s wear resistance while monitoring surface finish and tool life for final parameter optimisation.

FAQ

Which materials is this insert suitable for?
The XNMF090612‑F57 WKK25G milling insert is optimised for ISO group K, i.e. cast iron, with the grade tailored to resist abrasive wear and handle short, breaking chips.

What are the key benefits of the WKK25G grade?
WKK25G is a Tiger·tec Gold coated carbide grade developed by Walter Tools to deliver high wear resistance, stable edge life and productive machining in cast‑iron applications.

What is the purpose of the F57 chipbreaker?
The chipbreaker F57 produces short, controllable chips in cast iron, improving evacuation and reducing recutting, which in turn supports uninterrupted machining and safer handling.

How does the 0° negative rake affect cutting?
A 0° negative rake increases cutting‑edge strength for interrupted or heavy cuts; when combined with the 1.2 mm corner radius, it provides enhanced stability and a consistent surface finish.

What is the exact article identification and who supplies it?
The article is listed as XNMF090612‑F57 WKK25G (SKU: XNMF090612‑F57‑WKK25G‑WALTER) and is supplied by Walter Tools as a milling indexable insert for cast‑iron machining.
